[Elecraft] KPA500 Mod Kit?

[Petr, OK1RP/M0SIS]

Hi,

upon some emails regarding this modification procedure steps I am sharing
this note also over here on the reflector. (I am sorry if its bothering for
someone...)

I am recommending after several mods done - when Q5 is removed > do not
install new BU931T back to its place for now. Go to another step > remove
R5.
After that step solder the new BU931T transistor to Q5 position and follow
another steps normally.

If you will do it according to Elecraft manual then you will find that there
is quite small space around and it is too narrow to put your soldering tip
in between big transistors to remove the R5... You are also in risky to
damage parts by hot tip.

I am planning to put attention to my blog and modify my article accordingly
over here:

In case of troubles I can help with parts like transistors or other parts.
(I made this modification on several KPA500 for Elecrafters) 

Hope it will help.
